Alu Alu Cold Forming Aluminum Foil OPA/AL/PVC

Alu Alu Blister Foil Product Introduction

Cold forming aluminum foil, the scientific name is cold stamping forming the solid medicinal composite rigid sheet (commonly known as cold forming aluminum, alu alu foil, cold form alu alu foil).

Aluminum foil has a series of good properties, it is mainly used in three major fields such as medical packaging, electrical, and construction.

Among them, the demand for packaging is the largest, and the packaging takes medicinal blister packaging as an example. Medicinal blister packaging is generally made of medicinal cold-formed composite alu household foil.

Cold aluminum does aluminum foil keep things cold?

A processing technology of cold-formed aluminum foil is a production technology of cold-formed blister aluminum foil for aluminum composite, not an aluminum foil keep things cold.

Cold forming aluminum foil is first coated with composite glue on the surface of the nylon, and then enters the oven for treatment;

The preheated aluminum foil and the coated nylon are hot-pressed and compounded, and the matured semi-finished product is made after aging treatment

The semi-finished product is coated with composite glue again, Enter the oven and compound with PVC material, and then undergo curing treatment to form a finished product, so that the cold forming blister aluminum foil is made.

General structure of Alu-Alu blister foil

Composition: Alu-Alu blister foil typically consists of three layers:

Outer Layer: This layer is usually made of polyester (PET), which provides protection against external physical damage.

Middle Layer: The core layer is aluminum foil (alu), which acts as a barrier against moisture, oxygen, and light.

Inner Layer: The inner layer is usually made of polyvinyl chloride (PVC) or cold formable material. This layer comes into direct contact with the medication and ensures its safety and stability.

Reasons for the popularity of cold forming blister aluminum foil

1. This blister packaging allows each tablet to be individually packaged to provide patients with accurate dosage.
2. Alu alu foil packaging has good protection performance and high safety for medicines.
3. The production speed of cold forming aluminum foil packaging is fast, the degree of automation is high, and the cost is low.
4. Alu-alu foil for pharmaceutical packaging is not only convenient to carry, but also enhances the safety of medication;
5. Medicinal cold aluminum foil is light in weight, convenient to transport, good in safety, economical and practical.

Cold Form Foil Processing Technology

A processing technology of cold form alualu foil(alu alu low heat foil), involving the production of cold-formed blister aluminum foil for aluminum composite or jumbo reels alu foil.

First, composite glue is coated on the surface of OPA, and then enters the oven for treatment;

The preheated aluminum foil and the coated nylon Hot-press compounding, mature semi-finished products are made by curing treatment;

The semi-finished products are coated with compound glue again, enter the oven and compound with PVC materials, and then undergo curing treatment to form a finished product.

HWPFP Cold Formed Aluminum Foil Production Guarantee:

1. Ensure that the cold-formed aluminum foil is flat;
2. Strict requirements on the surface of the board, no black oil spots, scratches, small black threads, bright lines, roller printing bumps, mosquitoes, etc.;
3. Ensure that the cold aluminum foil has no holes;
4. Guarantee trimming, no burrs, towers, ruffles, flanging, bump lighting phenomenon;

Cold Forming Alu Foil Production Standard

It is made of environmentally friendly materials such as nylon (OPA) or polyester sheet (PET), aluminum foil(ALU), polyester sheet (PET), and imported glue, which are carefully developed, scientifically matched, and reasonable production technology.

Because it uses all high-barrier materials, the permeability of water vapor and oxygen is almost zero.

High barrier properties, safety, and non-toxic (no chlorine) are its biggest characteristics, which have a positive effect on the safety of medicines according to the guarantee.

Cold Forming Foil Characteristics

Barrier property: alu alu cold forming foil (also known as alu-alu foil cold forming) is currently the best barrier performance of medicinal hard films, which can almost completely isolate water vapor, oxygen, ultraviolet rays, and have excellent fragrance retention performance.
Advantages compared with traditional PVC: Each blister forms an independent unit that completely isolates water vapor, oxygen, and ultraviolet rays. Taking out part of the contents of a board of tablets has no effect on other well-packaged medicines in the same medicine board.
Appearance: concise, elegant, and beautiful, it is the preferred way of packaging health care products and medicines.
individual packaging: Each cold form blister forms an independent unit that completely isolates water vapor, oxygen, and ultraviolet rays, and part of the contents of a tablet is taken out, which has no effect on other well-packaged drugs in the same tablet.
